Sunto

L'etilacetato, data la sua liposolubilità, permea facilmente la membrana plasmatica dell'enterocita; all'interno della cellula, questa sostanza viene scissa in etanolo ed acetato dalle esterasi aspecifiche intracellulari. L'etilacetato, messo nel liquido di incubazione mucosale e serosale di un preparato in vitro di intestino tenue di criceto, stimola fortemente il trasporto netto transintestinale di sodio e di glucosio senza modificarne le concentrazioni intracellulari. L'azione stimolante di questa sostanza sembra quella di fornire energia metabolica alla cellula per effettuare un'estrusione attiva di sodio e di glucosio a livello della membrana basolaterale della cellula assorbente intestinale.
